In April 2008, Tom Brennan joined ARCH as a Venture Partner. He has special
focus on ARCH activities at Sandia National Laboratories and Los Alamos
National Laboratory. During his first year with ARCH, he served as an
Entrepreneur in Residence (EIR) at Sandia National Laboratories (SNL), a
position supported by a Department of Energy grant awarded to ARCH early in
2008.

Mr. Brennan began his career as a member of the technical staff at AT&T Bell
Labs, then joined Sandia in 1986 where he became a senior member of the
technical staff focused on the material growth of III-V semiconductor
materials and devices. Mr. Brennan's work included the growth of some of the
first 'vertical cavity surface-emitting laser' (VCSEL) material at Sandia
and in the U.S., and the development of new and unique VCSEL manufacturing
techniques. In 1994, Mr. Brennan and a colleague from SNL collaborated with
ARCH Managing Directors, Clint Bybee and Keith Crandell, to license the
VCSEL technology from SNL and co-founded MicroOptical Devices. Mr. Brennan
was Co-President of MODE through December 1997 when EMCORE Corp. acquired
MicroOptical Devices and established a new business unit called EMCORE
Photovoltaics, which Mr. Brennan started-up and led as its General Manager.

In 2001, Mr. Brennan was named President and CEO of Zia Laser, a spin-out
from the Center for High Technology Materials at the University of New
Mexico, which developed quantum dot laser diodes. He also served as Chairman
of Medical Lighting Solutions, which uses solid state lighting to treat
disease.

Mr. Brennan holds an A.S. in Chemistry from the Florida Institute of
Technology, a B.S. in Biochemistry from Monmouth College, and an M.S. in
Material Science from Steven’s Institute of Technology. He has published
